Hier möchte ich alle Benchmarks usw. sammeln. Bitte unbedingt das vorher lesen! Ich werde die Version des Images dabei schreiben. Einsetzen werde ich ausschließlich folgendes Image.

Macht bis jetzt für mich den stabilsten Eindruck.

USB2/3 (Version 0.7.3)
Ich benutze eine SAN Disk 240GB SSD an einem Inateck USB 3.0 2,5 Zoll Adapter.
Info zum USB-Adapter
lsusb Bus 004 Device 002: ID 174c:55aa ASMedia Technology Inc. ASM1051E SATA 6Gb/s bridge, ASM1053E SATA 6Gb/s bridge, ASM1153 SATA 3Gb/s bridge2,5 Zoll SSD am USB2-Port

Ich habe mich mit @tkaiser noch mal unterhalten. Scheint sehr deutlich ein Problem des Adapters zu sein. Da müsste eigentlich mehr gehen. Mal sehen....
